It had been a test. A whisper, hidden inside a patch, to see who was still paying attention to the machine beneath the machine.
No apology. No explanation.
The uninstall option for KB5087452 was grayed out. Microsoft, in its infinite wisdom, had marked it as ‘Permanent Security Baseline.’ You couldn’t roll back without a system restore point, and the update had helpfully deleted all restore points to save space.
